Some parents believe children should be paid for doing chores, while others think children should simply be assigned chores as part of being in the family. But even if children aren't paid in cash, they are paid in emotional benefits. Chores can begin at even very early ages. A three-year-old can help pick up toys spread out on his bedroom floor. Older children can be assigned to rake or mow their yards. Even driving younger siblings to different activities can be considered a chore.
